Created by SteveDitko, the Creeper first appeared in ''"Showcase''" #73 (April, 1968). He went on to star in his own short-lived magazine, suffered a couple of [[Main/RetCon retcons]] and [[Main/ReVision revisions]], and has done some guest appearances, never quite achieving wide popularity.

The original story tells about Jack Ryder, a Gotham City talk host who tries to save a scientist named Dr. Yatz from mobsters. An attempt to sneak in to the boss' mansion in probably one of the weirdest outfits ever, where Dr. Yatz was held during a masquerade, only got Ryder wounded and saved by Dr. Yatz who implanted him with a device that could make his costume disappear and with a serum that gave him super strength and agility, as well as the power to [[Main/HealingFactor heal almost instantly]]. It's also mentioned that his laughter makes people nervous or is even physically painful. Ryder could activate the suit (and apparently the superpowers, too, since he mentions not being so fast and strong in his normal form) whenever he wanted with a [[HammerSpace button-like object]].

Depending on the series, Creeper either acts like Ryder or is happily insane. Some versions explain the insanity by stating that he had a drug of some sort in his system at the time he had the device inserted, so the narcotic is recreated along with the costume.

The Creeper is also remarkable in being pretty much the only character SelfDemonstrating/TheJoker fears, which is one ''hell'' of an accomplishment.

[[IThoughtItMeant No relation]] to the walking green timebombs from ''VideoGame/{{Minecraft}}'', or the hunched-over hulk who constantly shouts his name from ''Franchise/ScoobyDoo'', or the monster from ''Film/JeepersCreepers''.

----
!!This character provides examples of:

* AbhorrentAdmirer: To Harley Quinn.
* ActionGirl: Fran definitely wasn't left out when the gang fought against Disruptor's men.
* AdaptationalVillainy: His {{New 52}} version is very much demonic, and even gets a VillainEpisode in ''JusticeLeagueDark'' during the ''ComicBook/ForeverEvil'' event.
* AmbiguouslyGay[=/=]CampStraight: [[DependingOnTheWriter Both may apply.]]
* BrownNote: DependingOnTheWriter, the Creeper's laugh can shatter anything from nerves to bones.
* TheCameo: Jack Ryder's voice can be heard on a radio on VideoGame/BatmanArkhamAsylum, and he appears as a minor supporting character in VideoGame/BatmanArkhamCity.
** One of the tapes unlocked by talking to Quincey in the church makes it clear that the Creeper and Huntress exist.
** He is also the source of a lot of discoverables in DCUniverseOnline, but he never turns into the Creeper.
* ClothingDamage: Averted later, but during his origin episode in the DCAU he was running around in severely torn clothes after his chemical bath until he got his costume.
* CrazyEnoughToWork
* CreepyGood: The guy is so batshit loco that even ''SelfDemonstrating/TheJoker'' considers him a lunatic!
** That's not enough, the Joker actually ''fears'' him. Let us reiterate that: THE MonsterClown of comics who terrifies millions has nightmares about ''this'' guy.
* DidYouJustPunchOutCthulhu: In the Batman TAS episde "Beware the Creeper", the Creeper meets Harley and immediately begins flirting with her. While doing so, he [[ExcuseMeWhileIMultitask nonchalantly uses one hand to punch out several of the Joker's mooks]]... and also gives an OffhandBackhand to ''Batman''.
* DramaticPause: ''I heard you guys worked for, [[SayingSoundEffectsOutLoud dramatic pause]], SelfDemonstrating/TheJoker!''
* EvenEvilHasStandards: A variation. The Joker (yeah, [[SelfDemonstrating/TheJoker that one]]) thinks he's uncontrollably insane, and wants the Creeper to get away from him, so it's more like "Even Insanity Has Standards."
* EvilLaugh: The New52 version.
* {{Expy}}: The Creeper's resemblance to Batman foe The Joker (both have green hair, clownlike faces and maniacal laughter) first pointed out in an issue of the latter's own comic book in the 1970's (where the two fought) may have led to the character's reinterpretation as being insane.
** Also, consider that The Creeper is remarkably similar to Ditko's own Loki, held over from Thor/Dr. Strange. They are very similar characters.
** In the animated series, The Creeper's design and personality is based on {{Freakazoid}}.
** That's because Freakazoid was originally The Creeper.
** If anything he is a nicer version of {{Deadpool}}.
** Or, in this case, {{Deadpool}} is a {{DarkerAndEdgier}} version of The Creeper
* FluffyFashionFeathers: The costume, famously, incorporates a ''giant red feather boa''.
* FunPersonified
* FutureBadass: A dystopian future that CaptainAtom appears in, during BrightestDay shows The Creeper still alive over 100 years later as a cyborg, and as noted, still insane.
* [[EvilCounterpart Good Counterpart]]: The {{DCAU}} version is this in respect to the Joker. In fact, he became the Creeper through the same vat of chemicals that made the Joker except he was also affected with Joker venom (in gaseous form). While both are goofy and dangerous, Joker relies on chemicals, gadgets and smarts while the Creeper has superhuman strength and endurace (taking a state dropped on him like nothing). Most of all, he retains a basic sense of right and wrong (when purchasing a new outfit, he paid with his credit card, which is what led to the discovery he was Jack Ryder.) Notably, he acts like a StalkerWithACrush towards Harley Quinn, mirroring her behavior towards the Joker.
** In the comics, [[UltimateShowdownOfUltimateDestiny they once meet, locked in the same room]]. The result? Joker ''begging'' to get out.
*** In the cartoon, the Creeper finally catches up to Joker and Harley at the end of the episode, ending with Creeper hurling Joker away, making him land at Batman's feet. Joker promptly grabs Batman's cape and screams "HE'S A LUNATIC!!", as if begging to be arrested.
** In the DCAU, he appears to eventually have joined the JusticeLeague, although sadly doesn't get any more speaking parts.
* HappyRain: In one story he ponders how he's always enjoyed being in the rain, and as Ryder even doing news reports during blizzards and typhoons.
* HealingFactor
* HeroesWantRedHeads: At least this is what Ryder's ex [[MistakenForCheating seems to think]]. ''"Switching from blondes to redheads now, you son-of-a--"''
* HeroWithBadPublicity
* ImpracticallyFancyOutfit: Kinda lampshaded; he actually chooses and buys his costume, assisted by a bored-looking shop attendant who looks as though half-naked psychopaths leaping in, trashing the store, asking for dress advice and paying by credit card is perfectly normal (well, this is Gotham...)
** Absolutely true: [[http://editthis.info/superdickery/Thriftie she has fans.]] It's mostly one guy, but it's also hilarious.
** It's also the most {{Stripperiffic}} of any male DCAU character. It's just boots, gloves, the boa and ''a speedo''. No, really. It makes a bit more sense in the DCAU than in the comics though, since he seems to have a very high dose of MadeOfIron in his powerset.
** In the original comics the costume was actually a full suit, the yellow part being spandex or similar (and it was also the last suit available in the shop) and the hair being a wig. It was also recognized to be a costume by some criminals, but since the doctor's device makes the costume stick like glue, trying to pull the wig off with no effect made them realize it to be the "real deal".
* IntrepidReporter: Occasionally, though more often than not comes off as a {{Paparazzi}}, to the point that at least once he gets scolded by [[{{Superman}} Clark Kent]].
** However, it was used to establish him before his actual origin episode (like with Harvey Dent, who was in at least three episodes before becoming Two-Face) in order to avoid too much RememberTheNewGuy.
* InvoluntaryShapeshifting:
** In ''ComicBook/BatmanGothamAdventures'' #58, the {{Diniverse}} Ryder is seen to shapeshift if he hasn't taken his medicine or due to a rush of adrenaline. He made the "change with a rush of adrenalin" thing work for him; once he needed to quickly transform, so he ''jumped out a skyscraper window!''
** Jack Ryder spent the good portion of one comic book spontaneously half-transforming into the Creeper without any control. His attempts to make himself scarce in the presence of his co-workers were entertaining.
* {{Keet}}
* LaughingMad: Sort of. Creeper's wild laughter made criminals extremely paranoid and nearly insane.
* LargeHam: Originally, Ryder would talk like a B-Movie horror villain when he was the Creeper to further confuse his enemies.
* LockingMacGyverInTheStoreCupboard: The very first comic origin.
* TheMadHatter
* MagicPants
* NighInvulnerable: In the Diniverse, the Creeper has a near identical origin as the Joker, yet he has managed to survive having a crate containing a rock statue the size of a car dropped on him, and going through multiple explosions without a single injury. Or hint of ClothingDamage. Also, he's able to send Batman flying with one punch, and break through walls. And easily dances around any attacks. Batman explains that this power is most likely due to a strange chemical reaction of the acid and the Joker's laughing gas (which may also explain why he retains a basic sense of right and wrong). The REAL reason for this though is just RuleOfFunny.
* NoCelebritiesWereHarmed: A rare unintentional example. Jack Ryder is a [[Creator/StephenColbert black haired, caucasian reporter,]] who, as noted in the StrawmanPolitical entry, is a left-wing political pundit, with a [[Series/TheColbertReport TV show that parodies right-wing political pundits]]. In a meta-sense, both were supporting characters for [[Franchise/{{Batman}} someone]] [[Series/TheDailyShow else]], whose popularity rose significantly from one or more TV appearances. Also, Google 'Stephen Colbert smiling', we'll wait.
* NoOSHACompliance: Subverted in the {{Diniverse}} origin. There were handrails, but nothing to stop Joker from pushing him over them.
* OffhandBackhand: To the [[MemeticMutation Goddamn Batman]], no less, in the Animated Series.
** Less of a backhand and more of an uppercut.
* PlotHole: Steve Niles' {{Retcon}} explains the change with nanocells, but the fact that Ryder can change to Creeper (who has his own set of "clothes") and back and still have his [[Main/MagicPants normal clothes]] is never explained or even lampshaded.
* RummageSaleReject
* ScrewySquirrel: Sometimes.
* SplitPersonality
* StalkerWithACrush
* StrawmanPolitical: In current continuity, Jack Ryder is a very outspoken left-wing pundit, whose show is called ''You Are WRONG!'' Though he did start to mellow a bit after becoming the Creeper.
* {{Stripperific}}: Usually found in just a Speedo and red boa.
* SuperSerum
* TalkativeLoon: In ''Batman: The Animated Series'' at least.
** Continuing the tradition in ''WesternAnimation/BatmanTheBraveAndTheBold''
* TerrorHero: In the original comics Creeper used to pull a scare shtick by pretending he was not human, describing the horrible fates of his enemies, laughing and acting weirdly to make his enemies panic (and loving every minute of it). This worked well enough that he actually managed to make one less hard-boiled guy faint.
** Played somewhat the same in the cartoons, namely because he is reminicent of the Joker.
* TooKinkyToTorture: Or insane at least, as is found out when he's tortured to test his pain threshold.
* TransformationTrinket
* UnderwearOfPower
* WallCrawl
* WallJump: Seen in ''WesternAnimation/BatmanTheBraveAndTheBold''
* WeatherControlMachine: Dr. Storme's weather rod.
* YoureInsane: Almost all times when doing something with (or near) other heroes and is usually treated with [[InsultBackfire "Yeah... Ain't it cool?"]] Also, need we remind you that the JOKER called him a lunatic?
